z j Application fi1ed June 21, 1917. Serial No. 176,120.

I! '0 all whom it may concern:

Be it known that I, Lmvnuncn HAUssIN- can, a citizen of the UnitedStates, residing at Alhambra, in the count y of Los Angeles and State ofCalifornia, have invented new and useful Improvements in CombinedBaby-Chairs and Common Chairs, of which the following is aspecification.

This invention relates to a chair and particularly pertains to acombined chair for adults and children.

It is the principal object of this invention to provide a chair of thestraight back type which may be used by adults and may also be convertedso that it will servethe purpose of a high chair and then used byinfants. 1

Another object of this invention is to provide a chair of the aboveclass, the convertible portions of which may be compactly folded so thatwhen the chair is used by adults it will have a sightly appearance andwill not disclose cumbersome and objectionable parts,

Anotherobject of this invention is to proride a chair having a seatwhich may be swung downwardly from the back of the chair and issupported by members which will catch in their lowermost position tohold the seat against. movement,

Another object of this invention is to pro vide a foldable tray supportmounted upon the seat supporting members and adapted to provide a safetyguard, as well as means upon which a tray may be detachably secured.

It is a further object of thisinvention to provide a chair adapted tobeused for the double purpose here specified, simple in construction,formed of few parts, and not liable to become easily broken.

Other objects will appear hereinafter.

The invention is illustrated, by Way of example, in the accompanyingdrawings in which:

Figure 1 is a View in perspective illustrating the chair andparticularly disclosing it as adjusted to accommodate an infant.

Fig. 2 is a fragmentary view in side elevation illustrating theauxiliary seat and the manner in which it is supported.

Fig. 3 is an enlarged view in section, as seen on the line 33 of Fig. 2,illustrating the detailed formation of the supporting arm catches.

Fig. 41 is a fragmentary view in perspective illustrating the back ofthe chair when the auxiliary seat is folded.

Referring more particularly to the drawings, 10 indicates a chair seat,here shown as being formed of a single piece of wood. Asis customary,this seat is supported by a pair of rigid front legs 11 and 12, and backlegs 18 and 14. The rear legs are formed with continuations producingposts 15 and 16. These posts are connected by cross braces 17 and 18 toform the chair back. Mounted between the cross braces are back rounds l9extending downwardly from the cross member 17 and terminating within anauxiliary cross brace 20. The chair thus constructed may be used byadults.

In order that the chair may be used by infants, an auxiliary seat member21 is provided. This member is substantially the same in shape as theseat 10, although of smaller dimensions and is pivotally connected tothe auxiliary brace 20 by means of hinges 22 and 23. As particularlyshown in Fig. 2, the hinges are not secured exactly along the edge ofthe seat 21, but are spaced a distance therefrom so that when the seatis down, a portion will swing beneath the auxiliary strip 20 and catchas the main portion of the seat hangs overthe strip 18, thus providing acombined lock and support which will relieve supporting members 24 and25 from excessive strains.

The supporting members 241 and 25 are each formed of two metal straps 26and 27. The upper straps 26 are pivotally secured to the outer round ofthe chair back by screws 28, while the lower straps are secured byscrews 29 to the sides of the auxil- .iary seat 21. The contiguous endsof the straps are bolted together by hinge bolts 30 which permit them tofold when the seat is in its uppermost position. Referring particularlyto Fig. 3 it will be seen that the lower end of the strap 26 is formedwith a lock recess 31 and that the adjacent end of the strap 27 isformed with a tongue 32 adapted to snap into the recess when the twostraps are longitudinally alined. A spring 33 is interposed between thenut of the bolt 30 and the side of the strap 27 so that the end of thestraps will be yieldably held in relation to each other and will permitthe tongue to easily snap in and out of the opening 31.

Cil

Mounted upon the bolts are tray arms 34: and 85 which are thus pivotedin relation to the supporting members and are connectcd by a cross piece36. The two arms and this piece form a U-shaped tray support, upon whichtrays may be rested and also which will act as a guard to prevent smallchildren from falling. The arms 3-1 and are provided with outturned lugs37 which engage the under side of thestraps 26 when swung down and holdthe entire tray support in a horizontal position.

In operation, the auxiliary seat stands in the position illustrated inFig. 4: of the drawings, and is held in position by a suitable snapfastener. In this position the chair will have a sightly appearance andwill be provided with a comfortable back formed by the braces 17 and 18and the auxiliary seat :21 which is swung up between the two braces, asshown.

IVhen the chair is to be converted for use as a high chair, theauxiliary seat 21 is swung dounwardl 1 from the back; As it swings down,the straps 2G and 27 forming the supporting members will swing out-*wardly from a folded position to one in which they are longitudinallyalined. When the seat is in its lowermost position, the tongues ofstraps 27 will snap into the recess '31 and lock the straps againstaccidental movement. It will be noted that as the supporting membersswing, the springs 83 will be held against rotation by the small iangs38-which project into longitudinal 7 slots 30 formed upon the faceof thestraps 527. hen the'chair has been swung down to its horizontalposition, the lower edge of the seat will be disposed beneath theauxiliary support 20 and the main portion of the seat adapted to restupon and overhang the cross brace 18. It will be noted that the crossmember 18 is formed with a beveled portion 42 to accommodate thedownwardly and rearwardly swinging edge of the auxiliary seat. If it isdesired to use the tray support, it may be swung down to a horizontalposition where its downward movement will be further limited by the lugs37; The bar 36' may then be swung across on its pivot and will be caughtat its free'end by a fastener 3%. When the seat is afterward folded, thestraps will be partially concealed, due to the fact that recesses -10and 41 be made by those skilled in the art without departing from thespirit of my invention.

I claim:

1. A chair having a set of supporting legs, a fixed seat secured to saidlegs, a back portion extending upwardly from the'seatg said back havingtransverse braces; an auxiliary seat adapted to be normally positionedbe tween said braces for vertical swinging movement, an intermediatebrace to which said auxiliary seat is hinged, means where- 'by the lowertransverse brace and the intermediate brace will rigidly support theseatwhen in its horizontal position, and folding side braces pivotallysecured to the chair back and to the forward end of the auxiliary seat.i

2. A chair havinga set of'supporting legs, a fixed seat secured to saidlegs, a back por- 7 tion extending upwardly from theseat and having sideposts between which are disposed transverse braces, an auxiliary seatnormally adapted to fill the space between said transverse braces, anintermediate transverse brace secured to said'posts and to which theseat is hinged for vertical swinging movement; said intermediate andlower transverse braces being so disposed that the rear edge of the seatwill swing befneath the intermediate brace and be heldby it and thelower transverse brace; folding side braces pivotally secured to eachother at their one ends and pivotally secured to the chair and the seatat their opposite ends so that they will be in longitudinal alinementwhen the auxiliary seat is horizontally disposed, and means fortemporarily locking said braces when in their unfolded positions. y

In testimony whereof. I have'signed my name to this specification; I
